Thanks Martin and Steve. I've just bought the book on kindle and checked out the website. It actually looks more difficult than I thought - everything I've been looking at says it's really hard to stay on the old route itself. Pity, but we'll try hard to make it authentic. Lots of planning to do, but two of our group are in semi-retirement and will have the time to research properly. If anyone else has done it, I'd quite like to hear any little tips.
